Broxton allowed a solo home run to D-Backs outfielder Gerardo Parra and a four-pitch walk to catcher Wil Nieves in the bottom of the eighth inning before being pulled in favor of closer Aroldis Chapman, who entered Wednesday without a six-out save in his career.
The Reds rendered Broxton unavailable to pitch on Monday and Tuesday because of an elbow issue, notes MLB.com's Mark Sheldon. The 29-year-old setup entered Wednesday with a 3.82 ERA in 30 ⅔ innings.
Broxton landed on the 15-day disabled list in June with an injury to his right elbow and didn't return until Aug. 9. In four appearances before Wednesday, Broxton did not allow a run and notched five strikeouts in 3 ⅔ innings since being activated.
